Bad at maths? Gorge on chocolates before you attempt your next
examination. A study from a few years back revealed that eating
chocolate could improve the brain’s ability to do maths as well as boost
your energy level. Researchers carried out the study in 2009 and found
that flavanols, compounds found in chocolate and part of a group of
chemicals called polyphenols, actually work by increasing the flow of
blood into the brain.

According to the study’s lead author David Kennedy of Northumbria
University, the findings suggest that students who binge on chocolate
when revising for examination might gain a real benefit from doing so
and chocolate could be beneficial for mentally challenging tasks also.
‘For things that are difficult to do, mentally demanding things that may
crop up in your work it could help,’ Prof Kennedy was quoted as saying.

In the study, 30 volunteers were asked to count backwards in groups
of three from a random number between 800 and 999 generated by a
computer. The findings showed that they could do the calculations more
quickly and accurately after they were given a hot cocoa drink
containing 500 mg flavanols. However, the same was not true when the
group was asked to count backwards in groups of seven, which the
researchers described as a more complex task, requiring a slightly
different part of the brain.

Kurtzvail ( 66 ), which is considered one of the world's leading
experts in artificial intelligence , and the technologists has
popularized his idea of ​​" singularity " - the moment in the future
when humans and machines become one.'' Google '' hired him end of 2012. to work on future projects of the company - a search engine that is
used artificial intelligence and knows us better than we know ourselves .In an interview with the Observer New Review, Kurtzvail says his company
has not given any explicit instructions , except that he was ordered to
find a way to " teach " Google to understand natural language ." My project is to start a search for understanding of the language ," he says ." When you write an article , you do not create an interesting collection of words . You have something to say and ' Google ' should be intelligently organized and processed information from around the world . The message in your article is the information , but that computers do not understand . Therefore , we want them to read everything there is on the internet
and each page of each book , so that they could participate in an
intelligent dialogue with customers and answer their questions, " he
explained.Kurtzvail predictions are only part of the earlier announcement that Google makes
the largest laboratory in the world of artificial intelligence . The company has acquired several companies engaged in " teaching "
machines and production of robots , including '' Boston Dynamics '' .Kurtzvail is known for his inventions that changed the world - the
first desktop scanner , the first computer program that is able to
recognize the first syllable fonts and speech synthesizer .It was in 1990. predicted that the computer would beat the world chess champion to in 1998. (
In 1997. IBM 's Deep Blue beat Garry Kasparov ) and the world wide web

Titan is one of the moons on Planet Saturn. It is said that here, the atmosphere is so thick and the gravity so low that you could fly through it like a bird does on Earth by flapping wings attached to your arms. This statement can be found in the book Entering Space: Creating a Spacefaring Civilization by Robert Zubrin.

Of course, the atmosphere on Titan would not be conducive for your health, so a spacesuit could come in handy. The Voyager has been able to make some observations that prove the atmosphere on Titan is denser than Earth’s, and this has been put at about 1.19 times as immense as Earth’s overall.

The lower gravity on Titan implies that the atmosphere extends way much more than Earth’s. This was even proven by the Cassini spacecraft that flying at a distance of 975 km, had to make adjustments to maintain a steady orbit against atmospheric drag.

Dr. Zubair said that the simulation showed that the stem cells are able to grow faster in zero gravity . He hopes the experiment on the International Space Station and to
prove it, and also to find out whether there is some abnormality in the
development of :"
When it stimulates the growth of cells, there is a danger of an
abnormality , which means that such a cell converted in carcinogen . Another factor that we want to examine is the transformation into malignant cells . "While one group of cells propagated in space , the other will develop on Earth . In addition to gravity , all the conditions will be the same .Zubair continues to colleagues examined the effects of gravity on stem cells . If the initial experiments are successful, and weightlessness show
appropriate for the growth of stem cells Zubair added , the next
challenge will be to transform cells in tissues and organs in the end .Zubair has already predicted that human bodies could easily grow in space and later , if necessary transplant :" Imagine , you can have a spare heart , kidney or liver , somewhere in the universe . Only someone on the phone when you need it . So from your stem cells obtain tissue or organ and use it when you need it . "While this can happen only a few decades , Zubair said that this research could affect the near future . If the cells are rapidly developing in the universe , adds Zubair , doctors would be better able to treat patients on Earth .

It
will open up the possibility of solving the mysteries of dark matter
and should find evidence of cosmic concept known as " supersymmetry " . It should find signs of hidden dimensions that can explain the existence of gravity.By the end of the year , a gigantic machine for colliding atoms should
have to increase energy particles from eight billion electro-volt to 14 tera elektronvolt, which will allow the most powerful particle
collisions so far .A new series of experiments should lead scientists outside the field of physics known as the " standard model" .Scientists may yet discover the Higgs boson - different versions of
the so-called " God particle " that is predicted Nobel Prize winner
Professor Peter Higgs and other particle gives mass .The Higgs boson was the last " missing fraction " of the "standard model " .Now scientists want to go a step further and explain the mysteries of the cosmos functioning .Professor Tony Doyle of the University of Glasgow , a leading member
of the team that manages the giant Atlas detector says that the current
priority is to explain supersymmetry .Super-symmetry to a hypothesis that the basis of each particle of
matter exist , and the particles bearing the appropriate force .This requires the existence of several Higgs bosons ." The universe is driven by supersymmetry key ideas . Currently separate the particles of matter and particles that carry force . Evidence of supersymmetry would change the way we look at space , "says Doyle.Survey Supersymmetry could explain the mystery of dark matter - the
invisible bond that holds galaxies together , and whose nature is still
unknown .More powerful large proportion Hadron Collider could offer scientists
an insight into the hidden dimensions and thus reveal the mystery of
gravity.Do 2020th the system will be changed so that the collider energy levels remain
the same, but the detectors become 10 times more sensitive .It is expected that the machine will be operative to 2030th.
